Abstract
Abstract The electrostatic solvent effects and hydrogen-bonding interactions on IR and UV absorption and fluorescence spectra of 1-methyl-2-pyridone has been investigated. It was found that the UV absorption and fluorescence bands of 1-methyl-2-pyridone shifted towards the shorter-wavelength region with increasing solvent polarity and that these bands exhibited a blue shift on hydrogen bond formation with alcohols and chloroform. The excited-state dipole moment of 1-methyl-2-pyridone, and the equilibrium constants in the ground and excited states and enthalpy change in the ground state for hydrogen-bond formation between 1-methyl-2-pyridone and ethanol have been determined from the spectroscopic studies.
